Embodiment Construction

[0019] refer to figure 1 and figure 2 . The present invention mainly is made up of following three parts:

[0020] 1. The main device: the shape is a cylinder 14, the bottom is a cone 21, and the top is added with a top cover 3 to form a closed space. Inside the device, the inner cylinder 17 separates the lower space from the inside and outside, forming a central reaction zone 18 and an outer annular sludge concentration zone 19 . An annular weir 16 is formed on the top of the inner cylinder 17 to provide a passage for excess sludge to be discharged from the reaction zone 18 into the concentration zone 19 . On the upper part of the annular weir 16, the interior of the device is separated up and down by a circular large-hole mesh plate 12, and an independent Lagpe ring filling area 10 is formed on the upper part. The top of the Lagpe ring filling area 10 is separated from the water collection area 9 by a screen 11 again. The reaction area 18, the annular mud discharge wei...

Abstract

The present invention discloses a high-effective solid-liquid separator formed of external cylinder, internal cylinder, cone body, Rasching ring, macropore screen, filter screen, mixing propeller, motor and packing particles. Said invention possesses the following advantages: its design is reasonable, structure is compact, reaction zone, separation zone and sludge-concentrating zone are placed in one cylinder body to eliminate unavailable space in the equipment, and minimize its volume, its cost is low and convenient for moving and operation, can effectively raise solid-liquid separation efficiency and can ensure that the treated water can reach the high water quality requirements.

Description

technical field [0001] The invention relates to a water supply and waste water treatment device, in particular to a high-efficiency solid-liquid separation device. technical background [0002] Solid-liquid separation is an essential part of water and wastewater treatment. The traditional solid-liquid separation process includes coagulation, sedimentation, filtration and other treatment units. When the concentration of suspended solids is high, a pre-sedimentation tank is required before coagulation. In addition, the separated sludge must be concentrated, so the process is long, the structure is huge, and the treatment cost is high. It is not suitable for small towns, small industrial enterprises and temporary or non-fixed occasions. In addition, in many areas, there is often an urgent need for water purification or temporary treatment of some wastewater, and it is required to provide treatment equipment with high efficiency, good treatment effect and good flexibility. Ther...
